LINER Fen TYPOGRAPHICAL CASTING MACHINES.

'. To an whom it may concern:

Be it known that I, LLOYD TLWII MANS, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain newand useful Improvements n Liners for Typographical is a specification. j

This invention relates to new and useful improvements in liners for typographical casting machines. j

' As is well known the length of a slugde Casting Machines, of which the following V pends upon the width. of the column in'which it is to be set, and as thecolumns vary in width'it' is customary to lengthen and shorten "the mold slot by removing the liner and inserting another either longer or shorter.

An ejector blade er e width substantially the same as the lengthof the slug is employed to eipel the slug' fr'omltheslot. 'Under ordi'-' nary practice it isnecessary to change the v .ticularly' when alonger liner for casting a "shorter slug. is substituted. It frequently happens that the operator forgets to change the ejector blade and consequently the liner is destroyed and: the expensive mold is often broken. 5

. metal. These changes which are well known, cause the casting of slugs with defective hottoms or slugs which are hollowl' When such conditions exist both the e ectorblade and slug have a tendency to bind in the mold,

whereby the slug becomes stuck and must be removedbefore the operation of the machine can be continued. These occurrences are frequent and, of course, cause a great loss of time, as well as damag ngthe liners.

A frequent result'is a bent liner with its face extending outwardly from the faceof themold. and theback of the liner. lying within the marginal'edge 'of' the slot; This permits the metal to flow inbehind the, liner,

thus producing a flash"- on' thefslugs which must be trimmed off. The face of the liner extending will interfere with the positioning 0f the matrices with relation to the mold and cause the casting'of defective slugs,

ly from the mold slot from a pivot or hinge and one which will also save said blade from injury.

Another object is to provide a liner capable of undergoing a slight longitudinal movement, whereby contact with a stuck slug is relieved and the liner permitted to swing slightly forward. The pressure on the end of the slug thus being relieved, the ejector will easily push out the slug without injury to the liner, mold, ejector blade or slug.

A further aim of the invention is to provide a hinged or pivoted liner which if displaced from the mold slot, may be readily swung back into the slot. The invention also contemplates the use of an extension linkand by use oflinks of different lengths,

to provide numerous adjustments with each I slot-accordingly. ejector blade when a liner is changed, par- An important advantage of the invention is the provisionof a liner that is practically indestructible and of long life. By

employing such a liner the usual stock of liners may be greatly reduced, likewise the investment. A great saving in time will be had as well as a reduction in repairs and the cost of maintenance of the machine. Further frequent delays will be entirely increased.

The invention will be more readily understood from a readingof the following specification and by reference to the accompanying drawings. in whichexamples of the invention are shown and wherein:

Fig.2 is a plan view of the mold withthe cap detached and illustrated the mannerin which an ejector of too great a width swings the liner out of the mold, f

Fig. v5 is a view similar to Fig. 2, showing a'modified form of liner, and l Fig. 6 is a perspective view of said modibetween the body an d cap atthe opposite end and the mold slot lhis thus formed between the parts12 and 13. The length and thick 7 ness of this is varied by changing the liners.

- An ejector blade 15 is adapted to enter the slotand eject the slug therefrom.

The invention'has to do with the liner, which it is to be understood may be pivoted in any suitable manner so as to swing out-" yvardly and to be again swung inwardly,
